Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für einen Fahrzeugsitz, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1 sowie einen Beschlag, der eine solche Verriegelungsvorrichtung aufweist, und einen Fahrzeugsitz mit wenigstens einem solchen Beschlag.The invention relates to a locking device for a vehicle seat, in particular for a motor vehicle seat, with the features of the preamble of claim 1 and a fitting, which has such a locking device, and a vehicle seat with at least one such fitting.

Eine aus der WO 01/76907 A1 bekannte Verriegelungsvorrichtung dieser Art verriegelt einen Beschlag zur Lehnenneigungseinstellung. Das Fangstück ist im Normalfall in Öffnungsrichtung des Verriegelungselementes im Abstand zu diesem angeordnet, während es in radialer Richtung des Verriegelungselements an diesem anliegt. Beim Entriegeln nimmt das Fangstück nach einem gewissen Schwenkweg den angekoppelten Spannexzenter mit. Im Crashfall stützt das Fangstück die Sperrklinke ab, während der Spannexzenter ausweichen kann. Im Falle einer Kopplung über eine Schlitz-Zapfen-Führung könnte eine Rückwirkung des Spannexzenters auf das Fangstück erfolgen.One from the WO 01/76907 A1 Known locking device of this type locks a fitting for Lehnenneigungseinstellung. The catching piece is normally arranged in the opening direction of the locking element at a distance to this, while it bears in the radial direction of the locking element at this. When unlocking takes the catch piece after a certain pivoting the coupled clamping eccentric. In the event of a crash, the catching piece supports the pawl, while the tensioning eccentric can escape. In the case of a coupling via a slot-pin guide a reaction of the clamping eccentric could take place on the catch piece.

Der Erfindung liegt die Aufgabe zu Grunde, eine Verriegelungsvorrichtung der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Verriegelungsvorrichtung mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is based on the object to improve a locking device of the type mentioned. This object is achieved by a locking device with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

Dadurch, dass ein dem Verriegelungselement zugeordneter Anschlag zum Zusammenwirken mit dem Spannexzenter im Crashfall vorgesehen ist, wobei im Falle des Zusammenwirkens des Spannexzenters und des Anschlags der Spannexzenter in Anlage an den Anschlag gelangt, bevor die Kopplung mit dem Fangstück wirksam wird, kann eine Ausweichbewegung des Spannexzenters im Crashfall gestoppt werden. Eine Rückwirkung auf das Fangstück, welche bei hohen Belastungsspitzen auftreten könnte, wobei das Fangstück durch eine Bewegung seine gewünschte Position verlassen könnte, kann ausgeschlossen werden. Damit kann die erfindungsgemäße Verriegelungsvorrichtung auch bei sehr hohen, impulsartigen Belastungen eingesetzt werden, beispielsweise in einem als Lehnenneigungseinsteller ausgebildeten Beschlag oder einer Schließvorrichtung zur Fahrzeugstrukturanbindung des Fahrzeugsitzes eingesetzt werden. Die Kopplung zwischen dem Fangstück und dem Spannexzenter über eine Schlitz-Zapfen-Führung oder ähnliche wegverzögernde Mittel hat den Vorteil, daß Bauraum eingespart werden kann.Due to the fact that a stop associated with the locking element is intended to cooperate with the clamping eccentric in the event of a crash, in which case the clamping eccentric comes into contact with the stop in the event of interaction between the clamping eccentric and the stop before the coupling with the catching piece becomes effective Spanxzenters be stopped in the event of a crash. A reaction to the catch piece, which could occur at high load peaks, wherein The catch piece could leave its desired position by a movement can be excluded. Thus, the locking device according to the invention can be used even at very high, pulse-like loads, for example, be used in a designed as Lehnenneigungseinsteller fitting or a locking device for vehicle structural connection of the vehicle seat. The coupling between the catching piece and the clamping eccentric via a slot-pin guide or similar path-delaying means has the advantage that space can be saved.

Der Anschlag ist vorzugsweise an einem Steuernocken vorgesehen, mit welchem der Spannexzenter zusammenwirkt und der mit dem Verriegelungselement verbunden ist, da dann - entsprechend ihrer Funktion - verschieden dicke Bauteile in verschiedenen Ebenen bauraumsparend angeordnet werden können. Zur einfacheren Herstellung ist der Anschlag vorzugsweise am Steuernocken angeformt, so daß er - kostenneutral - gleichzeitig mit diesem aus einem Blech ausgestanzt werden kann.The stopper is preferably provided on a control cam, with which the clamping eccentric cooperates and which is connected to the locking element, since then - according to their function - different thickness components can be arranged space-saving in different levels. For ease of manufacture, the stop is preferably formed on the control cam, so that it - cost-neutral - can be punched out of a metal sheet simultaneously with this.

Um jeglichen Impulsübertrag auf das Fangstück vor Anlage des Verriegelungselementes am Fangstück zu vermeiden, liegt das Fangstück im Normalfall an einem festen Anschlag an, der vorzugsweise an einem Bauteil, welches mit den diversen Lagern für die schwenkbaren Bauteile der Verriegelungsvorrichtung verbunden ist, angebracht ist, beispielsweise an einem Beschlagteil angebracht ist.In order to avoid any momentum transfer to the catching piece before contact of the locking element on the catching piece, the catching piece normally lies against a fixed stop which is preferably attached to a component which is connected to the various bearings for the pivotable components of the locking device, for example attached to a fitting part.

Ein Fahrzeugsitz 1 eines Kraftfahrzeuges ist zur Neigungseinstellung seiner Lehne 3 auf beiden Seiten mit einem Beschlag 5 versehen. Der Beschlag 5 weist ein sitzteilstrukturfestes Beschlagunterteil 7 und ein lehnenstrukturfestes Beschlagoberteil 8 auf, welches auf einem Lehnenlagerbolzen 9 relativ zum Beschlagunterteil 7 schwenkbar gelagert ist. Das Beschlagunterteil 7 besteht aus zwei plattenförmigen, parallelen Gehäuseteilen, welche zwischen sich einen Bauraum zur Aufnahme einer nachfolgend genauer beschriebenen Verriegelungsvorrichtung 11 zur Verfügung stellen.A vehicle seat 1 of a motor vehicle is provided for adjusting the inclination of its back 3 on both sides with a fitting 5. The fitting 5 has a seat part structure fixed fitting lower part 7 and a lean structure-fixed fitting upper part 8, which is pivotally mounted on a backrest bearing pin 9 relative to the lower fitting part 7. The lower fitting part 7 consists of two plate-shaped, parallel housing parts which provide a space between them for receiving a locking device 11 described in more detail below.

Auf einem Klinkenlagerbolzen 13 des Beschlagunterteils 7 ist eine Sperrklinke 15 als Verriegelungselement schwenkbar gelagert. Zum Verriegeln wirkt die Sperrklinke 15 mittels einer Verzahnung mit einem Zahnkranz 18 als Gegenelement zusammen, welcher am Beschlagoberteil 8 angeformt ist. Ein ebenfalls auf dem Klinkenlagerbolzen 13 gelagerter Steuernocken 19 ist mit der Sperrklinke 15 drehfest verbunden. Der Steuernocken 19 steuert in Zusammenwirken mit Steuerelementen des Beschlagoberteils 8 das Einfallen der Sperrklinke 15 in den Zahnkranz 18.On a pawl bearing pin 13 of the lower fitting part 7, a pawl 15 is pivotally mounted as a locking element. To lock the pawl 15 cooperates by means of a toothing with a ring gear 18 as a counter element, which is integrally formed on the upper fitting part 8. A likewise mounted on the pawl bearing pin 13 control cam 19 is rotatably connected to the pawl 15. The control cam 19 controls in cooperation with controls of the upper fitting part 8, the engagement of the pawl 15 in the ring gear 18th

Um den verriegelten Zustand der beschriebenen Elemente der Verriegelungsvorrichtung 11 zu sichern, sind verschiedene Sicherungselemente vorgesehen. Ein Spannexzenter 21 ist schwenkbar auf einem Exzenterlagerbolzen 23 gelagert und durch eine nicht näher dargestellte Feder in Schließrichtung belastet. Der mit einer bezüglich des Exzenterlagerbolzens 23 exzentrisch gekrümmten Spannfläche versehene Spannexzenter 21 wirkt auf den Steuernocken 19 ein, welcher die Sperrklinke 15 in den Zahnkranz 18 drückt. In der Ebene der Sperrklinke 15 ist auf dem Exzenterlagerbolzen 23 ein Fangstück 25 schwenkbar gelagert, welches federbelastet gegen einen fest mit dem Beschlagunterteil 7 verbundenen Anschlagsbolzen 27 gedrückt wird.In order to secure the locked state of the described elements of the locking device 11, various securing elements are provided. A clamping eccentric 21 is pivotally mounted on an eccentric bearing pin 23 and loaded by a spring not shown in the closing direction. The clamping eccentric 21 provided with an eccentrically curved clamping surface with respect to the eccentric bearing pin 23 acts on the control cam 19, which presses the pawl 15 into the ring gear 18. In the plane of the pawl 15, a catch piece 25 is pivotally mounted on the eccentric bearing pin 23, which spring-loaded against a fixedly connected to the lower fitting part 7 stop pin 27 is pressed.

Im beschriebenen verriegelten Zustand der Verriegelungsvorrichtung 11 ist das Fangstück 25 im Normalfall in einem geringen Abstand zur Sperrklinke I S auf deren vom Zahnkranz 18 abgewandten Seite angeordnet. Dieser Abstand ist geringer als die Zahnhöhe der Verzahnung der Sperrklinke 15 und des Zahnkranzes 18. Im Crashfall stützt das Fangstück 25 die mit einem öffnenden Moment belastete Sperrklinke 15 ab, so daß letztere nicht öffnen kann.In the described locked state of the locking device 11, the catching piece 25 is normally arranged at a small distance from the pawl I S on the side facing away from the ring gear 18 side. This distance is less than the tooth height of the teeth of the pawl 15 and the ring gear 18. In the event of a crash, the catching piece 25 supports the pawl 15 loaded with an opening moment, so that the latter can not open.

Zum Entriegeln der Verriegelungsvorrichtung 11 ist das Fangstück 25 mit einem Entriegelungsbolzen 29 versehen, welcher auf der einen Seite durch eine Kulisse des Beschlagunterteils 7 nach außen ragt und auf der anderen Seite durch ein Fenster 31 des Spannexzenters greift. Außer dieser Kopplung über den Entriegelungsbolzen 29 und das Fenster 31 sind der Spannexzenter 21 und das Fangstück 25 über eine Schlitz-Zapfen-Führung 33 miteinander gekoppelt. Beim Entriegeln wird zunächst das Fangstück 25 über den Entriegelungsbolzen 29 von der Sperrklinke 15 weggeschwenkt, wobei nach Erreichen des Randes des Fensters 31 durch den Entriegelungsbolzen 29 der Spannexzenter 21 wegverzögert mitgenommen wird und dieser den Steuernocken 19 und damit die Sperrklinke 15 freigibt.To unlock the locking device 11, the catching piece 25 is provided with an unlocking bolt 29 which projects on the one hand through a gate of the fitting lower part 7 to the outside and engages on the other side through a window 31 of the clamping eccentric. In addition to this coupling via the unlocking pin 29 and the window 31, the clamping eccentric 21 and the catching piece 25 are coupled together via a slot-pin guide 33. When unlocking the catching piece 25 is first pivoted away about the unlocking pin 29 of the pawl 15, wherein after reaching the edge of the window 31 by the unlocking pin 29 of the clamping eccentric 21 is taken away wegverzögert and this the control cam 19 and thus the pawl 15 releases.

Im Crashfall kann es sein, daß über die Lehne 3, das Beschlagoberteil 8, die Sperrklinke 15 und der Steuernocken 19 ein Impuls auf den Spannexzenter 21 gegeben wird. Da der Spannexzenter 21 außerhalb der Selbsthemmung am Steuernocken 19 anliegt, wird der Spannexzenter 21 durch den Impuls in Öffnungsrichtung stark beschleunigt. Um zu vermeiden, daß der Spannexzenter 21 über seine Kopplungen den Impuls auf das Fangstück 25 überträgt, insbesondere bevor letzteres die Sperrklinke 15 abstützen kann, ist am Steuernocken 19 ein Anschlag 35 vorgesehen. Der Anschlag 35 ist fingerförmig ausgebildet und am Steuernocken 19 auf der vom Beschlagoberteil 8 abgewandten Seite im Bereich des Klinkenlagerbolzens 13 angeformt. Der Spannexzenter 21 gelangt in Anlage an den Anschlag 35, bevor der Rand des Fensters 31 den Entriegelungsbolzen 29 berührt. Das Fangstück 25 bleibt somit in Ruhe und kann die Sperrklinke 15 abstützen.In the event of a crash, it may be that on the backrest 3, the upper fitting part 8, the pawl 15 and the control cam 19, a pulse is given to the clamping eccentric 21. Since the clamping eccentric 21 bears against the control cam 19 outside the self-locking, the clamping eccentric 21 is greatly accelerated by the impulse in the opening direction. In order to avoid that the clamping eccentric 21 transmits the pulse to the catching piece 25 via its couplings, in particular before the latter can support the pawl 15, a stop 35 is provided on the control cam 19. The stopper 35 is finger-shaped and the control cam 19 on the upper part of the fitting 8 side facing away formed in the region of the pawl bearing pin 13. The clamping eccentric 21 comes into contact with the stop 35 before the edge of the window 31 touches the unlocking pin 29. The catching piece 25 thus remains at rest and can support the pawl 15.
